this.mStage.addChild is not a function?

This is getting frustrating by the minute. This is very trivial nothing special. Every instance of object in my game receives a Container object. But everytime adding sprite within the constructor I get this error:

this.mStage.addChild is not a function:

I need help.

 

function SpaceShip(stage){	this.mStage = stage;		this.mSprite = new PIXI.Sprite.fromFrame("spaceship.png");	this.mSprite.anchor.x = 0.5;	this.mSprite.anchor.y = 0.5;		    this.mVelocity = 5;    this.mSprite.vx = 0;    this.mSprite.vy = 0;    	this.mFireRate = 10.0;	this.mCollisionRadius = this.mSprite.width / 2.0;	this.mIsMarkedDestroyed = false;		this.mBullets = [];	this.mLastCalledTime = Date.now();	this.mElapsed = 0.0;	this.mPixelPosition = {x : 0 , y : 0};	this.mOnPixelPositionChanged = function(lastPosition , newPosition){}		this.mStage.addChid(this.mSprite);}SpaceShip.prototype.markDestroyed = function(){	this.mIsMarkedDestroyed = true;}SpaceShip.prototype.isMarkedDestroyed = function(){	return this.mIsMarkedDestroyed;}SpaceShip.prototype.setOnPositionChanged = function(callback){	this.mOnPixelPositionChanged = callback;}SpaceShip.prototype.setPixelPosition = function (position){	var previousPosition = this.mPixelPosition;		this.mPixelPosition.x = position.x;	this.mPixelPosition.y = position.y;		this.mOnPixelPositionChanged(previousPosition , this.mPixelPosition);			this.mSprite.position.x = this.mPixelPosition.x;	this.mSprite.position.y = this.mPixelPosition.y;}SpaceShip.prototype.getSprite = function(){	return this.mSprite;}SpaceShip.prototype.getVelocity = function(){    return this.mVelocity;}SpaceShip.prototype.update = function(){	var delta = (new Date().getTime() - this.mLastCalledTime);	this.mLastCalledTime = new Date();	this.mElapsed += (delta / 1000.0);		if(this.mElapsed >= this.mFireRate)	{		this.fireBullet();		this.mElapsed = 0.0;	}		for(var bullets in this.mBullets)		bullets.update();}SpaceShip.prototype.fireBullet = function(){	this.mBullets.push(new Bullet(this , this.mStage))}function Bullet(spaceship , stage){	this.mSprite = new PIXI.Sprite.fromFrame("bullet.png");	this.mSprite.anchor.x = 0.5;	this.mSprite.anchor.y = 0.5;			this.mSprite.vx = 30;			this.mSprite.x = spaceship.getSprite().x;	this.mSprite.y = spaceship.getSprite().y;		stage.addChild(mSprite);}Bullet.prototype.update = function(){	this.mSprite.y += this.mSprite.vx;}

The error occurs initially at end before the '}' of SpaceShip(stage).

 

Thanks!
